Title: Mitigation of multipath effects in global positioning system receivers
Inventor: KNIGHT JERRY EUGENE
IPC: G01S19/30
Filed: 1996-05-24
Abstract: A technique for minimizing or eliminating the effect of multipath signals in a receiver processing pseudorandom (PRN) code signals, such as in a global positioning system (EPS) receiver. The presence of multipath signals adversely affects both node measurements and carrier phase measurements of received PRN signals. One aspect of the invention provides for improved code tracking in the presence of multipath signals, by sampling the received code with a multipath mitigation window (MMW) (FIG. 25D) that results in a code error function (FIG. 25F) that reduces or eliminates the multipath effects. The MMW, which stay by any of a number of preferred waveforms (FIGS. 35b-358), provides a code error function that varies in opposite directions from zero at a desired tracking point (402), but assumes a nearly zero value when the MMW is advanced from the tracking or synchronization point by more than a small fraction of a code chip. Because of this nearly zero code error value on the early side of the desired tracking paint, delayed multipath signals will have a corresponding code error function that is nearly zero (FIG. 25F) at the desired tracking point of the directly received signals, and the multipath signals will, therefore, have little or no effect on the desired tracking point and on code synchronization. The effects of multipath signals on carrier phase measurements are minimized by sampling the received signals, together with their possible multipath components, before and immediately after code transitions (vectors A and B respectively). The vector relationship of the directly received (D) and multipath (M) signals is such that performing a vector average of the two types of samples (A and B) produces the directly received signal (D) and its correct phase, with many, if not all, of the multipath components (M) eliminated.

Title: Inventory monitoring system
Inventor: GUDBJARTSSON LARUS
IPC: G06Q10/00
Filed: 2004-10-05
Abstract: An inventory monitoring system (100) measures changes in weight of an inventory (106) stored on one or more scales. The inventory items (108, 110) are divided into classes by weight, and the system (100) determines the maximum number of items that can be in a combination while maintaining a distinct combined weight. Items (108, 110) are then removed or added, and the change in weight on the scales (112) is correlated to a change in the number of inventory items (108, 110) to track the number of items (108, 110) removed or added over time. In a combined system (500), scanners (514, 516) are employed to track inventory received or sold, and data from the scanners (514, 516) relating to the items in the inventory is filtered out for comparison to the inventory changes indicated by changes in weight. The system has particular utility for monitoring inventories of cigarettes.

Abstract: An optical disk and a method for identifying the optical disk are provided which make it possible to identify a recording system of the optical disk easily in a short time by a recording and reproduction apparatus when a groove-recording system and a land-recording system are both employed in one kind of optical disk, for, example, a BD-R. Specifically, the polarity upon reproducing the wobble information is made to be the same in both of the optical disk of groove-recording system and the optical disk of land-recording system. The recording system of the optical disk that shows the same wobble polarity irrespective of the recording system can be easily detected by finding a tracking polarity that can recognize the wobble information by changing the tracking polarity, whereby the start-up time of the recording and reproduction apparatus can be shortened.
